Abstract. Organic materials (e.g. furfural residue) are generally believed to improve the physical and chemical properties of the soils with low fertility. Recently, biochar have been received more attention as a possible measure to improve the carbon balance and improve soil quality in some degraded soils. However, little is known about their different amelioration of a sandy saline soil. In this study, 56d incubation experiment was conducted to evaluate the influence of furfural and its biochar on the properties of saline soil. The results showed that both furfural and biochar greatly reduced pH, increased soil organic carbon (SOC) content and cation exchange capacity (CEC), and enhanced the available phosphorus (P) in the soil. Furfural is more efficient than biochar in reducing pH: 5% furfural lowered the soil pH by 0.5–0.8 (soil pH: 8.3–8.6), while 5% biochar decreased by 0.25–0.4 due to the loss of acidity in pyrolysis process. With respect to available P, 5% of the furfural addition increased available P content by 4–6 times in comparison to 2–5 times with biochar application. In reducing soil exchangeable sodium percentage (ESP), biochar is slightly superior to furfural because soil ESP reduced by 51% and 43% with 5% furfural and 5% biochar addition at the end of incubation. In addition, no significant differences were observed between furfural and biochar about their capacity to retain N, P in leaching solution and to increase CEC in soil. These facts may be caused by the relatively short incubation time. In general, furfural and biochar have different amendments depending on soil properties: furfural was more effectively to decrease pH and to increase available P, whereas biochar played a more important role in increasing SOC and reducing ESP of saline soil.

To find out the effect of low grade Udaipur rock phosphate on yield and nutrient dynamic in groundnut- maize cropping system, a field experiment was conducted in a randomized block design with three replications and eight treatments consisting of Udaipur rock phosphate (URP), single super phosphate (SSP) alone or in combinations with different ratios including phosphorus control from 2013-14 to 2015. The soil has a loam texture, a pH of 5.18, low available nitrogen and medium phosphorus and potassium. The highest maize equivalent yield of 6293 kg ha-1 and relative agronomic efficiency (RAE) of 159% was recorded in SSP+ lime (0.2LR) treatment followed by URP+SSP (1:1). Combined application of SSP+ lime recorded higher P, Ca, Mg and S uptake by groundnut-maize cropping system. When the crops received URP+SSP mixture in 1:1 ratio, the RAE values were increased above the standard SSP treatment (T3) being 102% for groundnut, 105% for maize and 103% for groundnut-maize cropping system. The yield in URP+SSP mixture (1:1) was higher than for the SSP treatment, but the difference was not statistically significant (P > 0.05). Thus, combined application of URP+SSP mixture (1:1) can safely be recommended in acid soils for short duration crops like maize and groundnut as against the more costly water soluble SSP fertilizer.

Global climate change and the increasing population have increased the difficulties associated with grain production. Several measures have been established to maintain a high crop yield, while preserving or increasing soil health, including biochar application to soil, and producing new complex soil with soil amendment application, e.g., biochar and soft rocks. However, previous studies have focused on the effect of complex soil on a single crop but have not considered crop rotation. In this study, field plots with foxtail millet cultivated for two years under biochar and soft rock application were selected for licorice cultivation to detect the effects of biochar and soft rock application on soil properties and licorice yield. The results showed that the biochar-treated plot had the highest licorice biomass (251.76 g/m2), followed by the combined biochar and soft rock treatment, and that the soft rock and control treatments had the lowest licorice biomass (97.65 g/m2). Plants in biochar-treated plots had the highest liquiritin and glycyrrhizic acid contents, followed by those under soft rock treatment. Soft rocks and biochar increased the soil catalase activity, organic matter, oxalic acid, tartaric acid, formic acid, and available phosphorus (AP). Correlation analysis showed that the licorice biomass was significantly positively correlated with oxalic acid and AP and negatively correlated with soil pH. AP was positively correlated with catalase activity and oxalic acid (p < 0.05) and negatively correlated with soil pH (p < 0.05). Therefore, it can be concluded that the addition of biochar and soft rocks for two years could increase soil organic acid contents (especially that of oxalic acid), which function to reduce soil pH, increase soil AP content, and enhance licorice biomass.

A glasshouse trial was performed to determine changes in phosphorus (P) nutrition and the yield of sword bean (Canavalia ensiformis (L.) DC.) following the application of different rates and types of P fertilizer in an acid upland soil of East Lampung. Two different types of P fertilizer, namely SP-36 (total P = 36%) and Phosphate Rock (PR) (total P = 24.3%, particle size distribution = 75% <0.25 mm, 85% < 0.50 mm, 90% < 1.00 mm) were used in the trial. For the treatment, each P fertilizer type consisted of four rates (0, 50, 100 and 150 mg P2O5 kg-1 soil) that were arranged in a Completely Randomized Design with four replications. The results showed that the application of P fertilizers had significant effects on soil pH, soil plant-available P, the potential-P (HCl 25%), leaf N and P concentrations, the yield of sword bean. Increased rates of both forms of P fertilizer increased the soil pH values. As the soil used had low pH and very high exchangeable Al, hence, this result is most probably related to the addition of Ca2+ to the soil solution that resulted from the P fertiliser applied (liming effect), either from SP-36 (monocalcium phosphate) or PR (flour apatite). There was no difference in soil available P concentration due to the different in P fertilizer types, indicating that 4 months after the fertilizer application, the relatively insoluble Phosphate Rock had the same P solubility with SP-36. Increased rates of both forms of P fertilizer increased the sword bean yield. For the application of 0 kg P2O5 ha-1, although sword bean crops had pods, but, they did not give any seed. Whereas, at the addition of P fertilizer at the rate of 50, 100, and 150 kg P2O5 ha-1 for both P fertilizer types, the crops were able to give the seeds in the pods. [How to Cite: Achmad AR. 2015.

An experiment involving sixteen treatments with four levels of phytase (0, 240, 480, 720 IU) and four levels of phosphorus (0, 25, 50, 100 kg ha-1) was carried out during kharif 2017 to assess the availability of phosphorus at 0, 15, 30, 45, 60 and 90 days (DAI) after incubation. There was an increase in soil available phosphorus up to 45th days of incubation either with the application of phytase or P and it reduced after 60 days of incubation. Significantly higher (12.98 kg ha-1) available phosphorus was observed with the application of phytase @ 720 IU (16.14 kg ha-1) and phosphatic fertilizer @ 100 kg ha-1within 24 hours of incubation over initial available P (5.20 kg ha-1). Application of 480 IU phytase resulted in significantly higher available P (51.98 kg ha-1) which was at par with 720 IU (50.45 kg ha-1). However, combined application of either 480 or 720 IU phytase along with either 50 or 100 kg P ha-1 through single super phosphate (SSP) had in statistically at par results for available phosphorus. Higher cumulative available phosphorus was recorded with the application of phytase @ 720 IU along with 100 kg P ha-1 through SSP (247.23 kg ha-1) throughout the incubation period. Further phosphorus release potential indicated that application of phytase @ 720 IU along with 100 kg P ha-1 through SSP mobilized 0.65 kg ha-1 day-1 phosphorus.

A field experiment was conducted in 2011 – 2013 in Poland. The objective of this study was to determine the effect of increasing doses of meat and bone meal (MBM) on the mineral nitrogen (Nmin) and available phosphorus (P) content of soil and the soil pH. Changes in the content of NH4+-N, NO3--N and available P in soil were affected by MBM dose, experiment duration, weather conditions and crop species. Soil amended with MBM was more abundant in mineral N and available P. The lowest concentration of NO3--N and the highest concentration of NH4+-N were noted in the first year of the study, because the nitrification process requires a longer time. MBM had no influence on the accumulation of Nmin in soil, whereas the concentration of available P increased significantly throughout the experiment. The soil pH decreased with increasing MBM doses. After the application of the highest MBM doses soil pH classification was changed from neutral to slightly acidic.

Biochar, a carbon-rich product of pyrolyzed biomass, has been used as an amendment to improve the properties of marginal highly-weathered soils in the tropics characterized by widespread phosphorus (P) deficiency. Alfisols derived from charnockite in Ekiti State are typically deficient in available phosphorus. Two alfisols from Ire-Ekiti and Ijan-Ekiti were amended with 0 (P-only), 5, 10 and 20% (w/w) biochars from maize stover (mB) and sawmill waste (sB) and incubated for 56 days with the addition of 60 mg kg-1 P in solution and a control without biochar and P-solution. Incubated soils were sampled fortnightly and analyzed for available P using Mehlich III extractant, pH, and electrical conductivity (EC) in water (1:2 w/v). Results show that biochar increased the soil pH by 1-2 units and EC from the native 0.02 to 8.37 dS m-1 with mB at 10 and 20%, causing soil salinity (EC > four dS m-1). Biochar increased available P to values ranging from 9.96 to 376.22 mg kg-1 compared to 2.93 to 7.64 mg kg-1 in control and 5.42 to 40.13 mg kg-1nin P-only treatments. The available P increased with days of incubation up to day 42 and followed by a slight decline, but the P in biochar-treated soils was significantly higher than other treatments. The mB significantly improved soil properties (soil pH, EC, and available P status), particularly at higher rates more than sB. The 5% mB in which the problem of salinity problem associated with higher rates is avoided should be recommended.
